        auth_param negotiate program /usr/local/libexec/squid/negotiate_kerberos_auth -d -k /usr/local/etc/squid/squidkeytab.keytab
        auth_param negotiate children 1000
        auth_param negotiate keep_alive on
        acl auth proxy_auth REQUIRED
        http_access deny auth
        http_access allow auth

        name is squidkeytab.keytab and not squidproxy.keytabb ?

            This is the ticket that should appear in klist..

            Everything seems to be OK with your configuration, at least between pfsense and AD.

            Show squid logs again after changing the keytab.
            Can you test with another client?

                Did you create the user and enabled it in AD ?

                    Maybe you are facing the same problem as this guy was, take a look:

                    http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-kerb-auth-received-type-1-NTLM-token-td2131613.html

                    Quote:
                    You should see a request from the client to Active Directory asking for a TGS for HTTP/<fqdn of proxy>. If that does not happen or get refused by AD the client will fall back to NTLM (wrapped into the Negotiate response) which is waht you see on the proxy.

                    I would set a packet capture like that guy did to check, port 88

                        Why are you authenticating as administrador@CASA.LOCAL ?
                        The user should be appearing there and not administrator. Should be user@CASA.LOCAL

                        The user need to be member of the group used in ldapusersearch in Squidguard

                          its because im opening the chrome inside of the windows server which im logged on as administrador

                          this is another user

                            Ok, in this last screenshot, the username is Windows10?
                            Is this user a member of the group used in ldapusersearch?

                            You are almost there.. soon we will find the problem

                              so on the squidguard

                              ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                              and the user is located in

                              CN=windows10,CN=Users,DC=casa,DC=local

                                ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                                You used a %2c in the wrong place (It means a ',')

                                It should be:

                                ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                                It's important to notice that you are not filtering users by group in this case..
                                I would create a group, like internet, add the members to this group, and then filter like this:

                                ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                                  @mcury said in Kerberos Squid without authentication?:

                                  ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                                  Thanks again for the reply, so i changed to

                                  ldapusersearch ldap://apolo.casa.local:3268/dc=casa,dc=local?userPrincipalName?sub?(&(memberof=CN=internet%2cCN=Users%2cDC=casa%2cDC=local)(userPrincipalName=%s))

                                  then created group called internet added windows10 and administrador but same issue with popup

                                  CN=internet,CN=Users,DC=casa,DC=local

                                  Im thinking its a squid issue but dont know what else to do :(

                                    Try port 389 instead of 3268.. Who knows..

                                        So, is it working now ?

                                        if not, I would focus on the ldapusersearch..

                                            Try to tick that option in squidguard: Strip NT domain name.
                                            If ticking it doesn't work, undo it..
